In the wake of the May 12, 2008, earthquake in China, a series of landslides blocked the Jiangjiang River, creating swollen reservoirs that threatened to break through and flood catastrophically. The largest of these lakes, Tangjiashan Lake, threatened roughly 1.3 million people. Chinese authorities faced a dilemma. If they allowed the water to keep rising, it would eventually overtop the dam and flood downstream communities...

The Strait of Messina Bridge Project, if completed, would stand as one of the landmark bridges of the 21st century. It would be the longest suspension bridge ever built. The Strait of Messina divides the island of Sicily from Calabria in southern Italy, and is 3 km wide. While the overall length is not a big problem, the economics, water depth, wind, and earthquakes all have to be accounted for. To avoid the problem of the deep water, the solution was to design the longest suspension bridge ever...

About 375 million years ago, Canada's Ellesmere Island looked very different. It enjoyed a subtropical climate on a massive continent, with big www.ucmp.berkeley.edu/plants/pterophyta/pteridopsida.html ferns and giant www.ucmp.berkeley.edu/plants/sphenophyta/sphenophyta.html horsetails . Not only did the landscape look different, so did the animals. Rummaging around in the shallow waters, occasionally poking their heads up for gulps of air, some fish sported legs...

Utah's Green River cuts across the Tavaputs Plateau (top) before entering rugged Desolation Canyon (center), which cuts southward through first the Roan and then the Book Cliffs -- two long, staircase-like escarpments that run west-east from Utah into Colorado. Desolation Canyon, seen in the center of this image, was named by the famous American explorer John Wesley Powell, for its intimidating, rugged terrain...

Satellite remote sensors view the Earth at many scales of space, ranging from global through continental, regional, and local--even observing details as small as one meter (three feet) across. These data enable scientists to study a wide range of phenomena that occur over these same scales of space, such as El Nino, droughts, storms, and flash floods. The above image shows the Hollywood sign above Los Angeles, California...

|Aftermath of Hurricane Isabel: Image of the Day - NASA -- Images provided courtesy of the edc.usgs.gov/ USGS EROS Data Center and the Landsat Project Science Office at NASA/GSFC|
The Atlantic's powerful waters gouged a new inlet across Hatteras Island in North Carolina's Outer Banks on September 18, 2003, when Hurricane Isabel came ashore. The top image, taken by the Landsat 5 satellite on September 26, 2003, shows how the storm split Hatteras Island in two. The bottom image, taken on October 25, 1999, shows the southern tip of Hatteras Island before Isabel wrought her damage...

|Microwave Imager Measures Sea Surface Temperature Through Clouds : Image of the Day - NASA -- Image courtesy TRMM Project, Remote Sensing Systems, and Scientific Visualization Studio, NASA Goddard Space Flight Center|
This image was acquired over Tropical Atlantic and U.S. East Coast regions on Aug. 22 - Sept. 23, 1998. Cloud data were collected by the Geostationary Operational Environmental Satellite (GOES). Sea Surface Temperature (SST) data were collected aboard the NASA/NASDA Tropical Rainfall Measuring Mission (TRMM) satellite by The TRMM Microwave Imager (TMI). TMI is the first satellite microwave sensor capable of accurately measuring sea surface temperature through clouds, as shown in this scene...
